Limestone has been currently used as a desulfuriser to capture SOx emitted from fluidized bed coal combustors. The limestone mainly consists of CaCO_3, which is also contained in seashells. Considering this similarity, desulfurization characteristics of the seashells and limestone were compared in our previous study. From the results obtained, the desulfurization efficiency of seashell was over twice higher than that of limestone. The reason of high desulfurization efficiency of seashell is caused by high alkali content in the seashells. In the present study, molecular dynamics (MD) simulations will be useful to study that relationship theoretically. Therefore, we adopted MD simulations relating to CaO structure. In the simulation, two cases of CaO alone and CaO-NaCl or KCl systems were analyzed in order to elucidate change of the molecular structure for CaO due to the alkali addition.

In coal-fired combined power generation systems like pressurized fluidized bed combustion (PFBC), vapor-phase alkali metal compounds from coal contaminate the reaction gas, which may cause hot corrosion of turbine blades. In this study, evolution behaviors of the alkali metal compounds, especially for sodium compounds, in coal combustion were elucidated, sampling and shifting the fine particulates in the combustion process and analyzing the sodium concentration. Concentration of fine particulates and distribution of sodium concentration in the particulates depended on coal type. The mechanism of sodium enrichment was estimated by the result of sodium concentration in the particulates shifted.
